Multishot diffusion-weighted PROPELLER magnetic resonance imaging of the abdomen.
OBJECTIVE The objective of this study was to evaluate the feasibility of using multishot PROPELLER for diffusion-weighted imaging (DWI) of the abdomen. MATERIALS AND METHODS Diffusion-weighted abdominal imaging was performed in 9 healthy volunteers and 3 patients using both single-shot DW-SE-EPI and multishot DW-PROPELLER (BLADE sequence). We compared ADC measurements in phantoms, liver and p...

متن کاملImage domain Propeller FSE (iProp-FSE)
Introduction: Fast-spin echo (FSE) imaging is one of the most frequently used pulse sequences for brain imaging due to its scan time efficiency, good tissue contrast, and high effective resolution. Practical problems that occur are mostly due to patient motion, which leads to blurring and imaging ghosting (Fig. 1b). To make the acquisition robust to motion, the T2-w PROPELLER pulse sequence can...
متن کاملCompressed Sensing in Diffusion-Weighted Radial-FSE
Introduction Radial fast spin-echo (Radial-FSE) methods have been used to produce high-resolution diffusion-weighted images that are insensitive to motion and/or magnetic field inhomogeneity [1,2]. However, one of the drawbacks of radial-FSE is the long acquisition time, compared to single shot echo planar imaging, required for high resolution images with sufficient signal to noise ratio (SNR)....
